Knee, Femur, & Tib/Fib Imaging

These flashcards cover essential vocabulary and key concepts related to knee, femur, and tib/fib imaging as discussed in the lecture notes.

Anterior Cruciate Ligament (ACL)

A ligament that arises from the medial intercondylar tubercle and attaches to the posteromedial surface of the lateral femoral condyle, helping to prevent hyperextension and anterior displacement of the tibia.

Posterior Cruciate Ligament (PCL)

The ligament that extends from the posterior aspect of the intercondylar eminence to the anteromedial surface of the medial femoral condyle, preventing hyperflexion and posterior displacement of the tibia.

Lateral Collateral Ligament (LCL)

Ligament that arises from the lateral femoral epicondyle and attaches to the head of the fibula.

Medial Collateral Ligament (MCL)

Ligament that originates from the medial femoral epicondyle and extends to the medial tibial condyle, continuing to the medial shaft of the tibia.

Coronal Plane Imaging

Imaging slices that are angled parallel to the posterior surfaces of the femoral condyles, useful for detecting meniscal lesions and disruption of collateral ligaments.

Sagittal Plane Imaging

Imaging slices that are angled parallel with the ACL, used to detect lesions of the cruciate ligaments, menisci, popliteal cysts, and patellar tendon injuries.

Axial Plane Imaging

Imaging slices that are angled perpendicular to the posterior surfaces of the femoral condyles, used for patellar tracking problems and identifying chondral damage.

STIR Pulse Sequence

A method used in MRI to produce images with less artifact, particularly useful when metallic implants are present.

MRI Artifacts

Unwanted distortions or errors in MRI images due to factors like patient motion, flow from blood vessels, or metal presence.

Baker Cyst

A type of popliteal cyst that can be detected in knee MRI, causing swelling behind the knee.
